5G Radio Access network planning is a process of proposing location of sites, configuration and settings of the network nodes to be rolled out in a wireless network. Radio network planning objectives are fulfilled by proper selection of site locations, configurations and settings of all parameters including antenna heights, azimuths, angles etc. In 5G, automated site selection and configuration is becoming a must in 5G NR planning as the number of cells deployed are much higher than previous wireless technologies. The process of planning is carried out by its RF design and the use of planning tool to carry out design. 5G NR provides operators with additional options for designing multi-layer networks by adding small cells to boost capacity and to deliver new services. Multi-RAT planning is the planning of multiple layers as a single network.
